Core Idea
Every box is a reward desk with clear entry rules. A user needs enough $BOX to access the desk, then spends $BOX to open. Market Box is the first live desk because it is easy to understand, easy to fund, and gives the vault time to build history before larger tiers open.
The system is not designed around unlimited positive expected value. It is designed around entertainment, transparent odds, token burns, and a reserve that can survive bad streaks. That is why each box has a published house edge and why higher tiers unlock only as liquidity and treasury depth improve.
01HOLD
Hold enough $BOX to enter a box desk. Market Box starts at 10,000 $BOX.
02OPEN
Opening a Market Box costs 10,000 $BOX. 5% burns, 95% moves to the Reward Reserve.
03REVEAL
Your box is sealed when you pay, then scored by the hash of a block mined afterwards. Nobody can predict or influence the result, and the reveal transaction is public.
04CLAIM
Claiming is free. You receive the actual stock: an SPY box pays tokenized SPY, an NVDA box pays tokenized NVDA, sent automatically to the wallet that opened the box.

The burn side reduces circulating supply pressure. The reserve side gives the project a growing war chest for claims, vault depth, LP support, and future reward epochs.
What Claiming Costs
Nothing. The open fee is the only thing you pay. There is no claim fee, no burn on winnings, and no withdrawal charge — the reward shown at reveal is exactly what lands in your wallet.
For launch, Market Box rewards are small on purpose. The first goal is to prove opens, claims, treasury controls, and user trust before larger inventory goes live.

RARITYODDSREWARD
COMMON75.00%$0.44
RARE20.00%$1.35
EPIC4.50%$4.56
LEGENDARY0.50%$25.00
Win rate: 25% of Market Box opens return more than the open cost. The other 75% return $0.44 against a $1.00 open. House edge and win rate are separate things — the edge is how much of the pot the house keeps, the win rate is how those payouts are shaped. Most of the reward budget sits in the Epic and Legendary tiers, so a typical session is down even though the edge is small.
Probability math: 75.00% x $0.44 + 20.00% x $1.35 + 4.50% x $4.56 + 0.50% x $25.00 = about $0.93 of gross reward budget against a $1.00 open at 10,000 $BOX per dollar. That is the published 7.0% house edge, measured against everything the player pays.
House Edge Ladder
MARKET BOX7.0%Launch desk, fastest access, highest reserve growth.
AI BOX6.0%Sector desk for AI and semiconductor exposure.
MEME BOX5.0%Event desk for volatility and culture trades.
WHALE BOX4.0%Higher holder tier with deeper reward batches.
BLACK BOX3.0%Limited desk for the largest holders and special epochs.
The displayed house edge is the target protocol edge for funded reward batches. Market Box starts at 7% while the reserve is young. As market cap, liquidity, and treasury depth grow, rewards can expand, additional desks can open, and house edge can step lower where the vault can support it.
Snapshot Bonuses
Holders in the first 48 hours receive bonus consideration. Snapshot bonus details, reward multipliers, and any desk-specific boosts are released after the snapshot window so the launch does not reward last-block borrowing.
Claims And Settlement
Rewards settle in Robinhood Stock Tokens on Robinhood Chain — the same ERC-20s that trade on the chain’s DEXs. The dollar figure on a tier is what the reward is worth; the amount of stock is priced at claim time, so $25 of NVDA means $25 of NVDA on the day you win it. A price far below its reference holds the payout for review rather than overpaying from a pushed market.
Randomness
Reveals use a VRF-style randomness layer built from public request data and sealed epoch entropy. The result is checked against the published odds table before payout, so edited browser values or replayed claims cannot clear.
Admin Controls
Claims are paid automatically when the payout wallet is funded and configured. The protected admin dashboard remains available for settlement review, denied claims, and any payout that needs operator follow-up.
Onchain Events
The opener contract is structured around readable activity: box opens, claim requests, claim settlements, and denied claims. That gives holders public transaction history while keeping treasury movement controlled.
Important Notes
STOCKBOX is an independent experimental project deployed around Robinhood Chain culture. It is not affiliated with or endorsed by Robinhood. Box opens are high risk, rewards depend on funded vault capacity, and nothing in these docs is financial advice.
